WATERHEATER AND TANK.

SPECIFICATION forming part Of Letters Patent N0. 636,799, dated November 14:, 1899.

Application filed 'E'ebruary 18, 1899. Serial No- 706,037. (N0 model.)

To all whom it may concern.-

Be it known that I, HENRY HARBECKES, a citizen of the United States,residin g in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Water Heaters and Tanks, which improvementis fully set forth in the following specification and accompanying drawlugs.

This invention relates to water-heaters; and it consists of a novel construction of tank and heating apparatus .whereby the heat units are efiectively utilized and the water expeditiously heated, a further object of the invention being to furnish a water-heater that can be connected with and operated by the usual range and stove or which can be disconnected therefrom and independently operated, provision being made by the employment of a lower flattened water-heating chamber for positively causing an upward circulation in the pipe which leads therefrom through the center of the Water-tank and a downward circulation through the outer portion of the Water-tank, a connection being made from the lower portion of said water-tank to the lower portion of said heating-chamber.

The invention further consists of the details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claim.

Figure 1 represents a side elevation of a water-heater embodying myinveution.- Fig. 2 is a central vertical section thereof.

Similar letters of reference indicate corresponding parts in the drawings.

Referring to the drawings, A designates a water-tank mounted upon a stand B and having a central upright flue O and a water-supply pipe D. Situated below the tank A is a heating=chamber E, communicating with the lower end of said tank by means of a pipe F, leading from the side of the tank tot-he bottom of the chamber E, said heating-chamber being preferably of a flattened shape and of considerable area as compared with the inletpipe F, whereby a comparatively thin body of water of considerable lateral or horizontal area is always exposed to the cfiect of the heating medium. The chamber E also communicates with the upper end of the tank by means of a pipe G, leading from the upper side of said chamber and passing through the flue O and connecting with the upper end of the tank. A service-pipe H leads from the upper end of pipe G and may also be provided with a branch J for connection with the heating apparatus of a stove or range, although it is understood that the present Water-heater can be used independently. The pipe F may also have a branch K connecting with the heating apparatus of .a stove or range, and a pipe L serves as means for draining the tank, heating-chamber, and water system.

A burner M, preferably for gas, is situated below the chamber E to direct the flame against the lower side thereof, and a hood N covers and surrounds the chamber E to direct the passage of the heated gases from the burner. The top of the hood-N is provided With a central opening and a depending flange P, having openings Q. The flange rests upon the top of the chamber E, with the opening in the hood concentric with the flue O. The hood is preferably of metal, with an interior lining R, of asbestos, and is situated close to the top and sides of the chamber E to direct the heated gases in intimate contact there with.

The chamber E is provided with an interiorly-screw-threaded hub S at its top to receive the lower end of the pipe G, and in the bottom of the chamber is a larger opening T, having a bushing U, forming the union with pipe F. By removing said bushing it is obvious that the interior of the chamber can be cleaned as occasion may require.

The operation is as follows: When this ap paratus is employed independently of a stove or range, it is understood that the pipes J and K arenot employed. In operation the drain-pipe L is of course closed and the Water entering from the pipe D fills the heating-cham her and water system. The burnerflame is directed primarily against the bottom of the chamber E and thereafter passes around and over the chamber, being confined by the hood N, and thence into the fine 0. The products of combustion can be suitably conducted from the top of the flue C, if necessary, although the combustion will be such that such expedient may not be necessary. It is thus seen that the chamber E first uti1= izes the heat units and that the heated gases passing under the flue the same are further absorbed by the water within the pipe Gand the tank A, as is evident. The water circulates upwardly from the chamber E through the pipe G, and thence to the upper end of the tank A, and from the bottom of said tank through the pipe F into the chamber E, while the consumption of hot water and supply of cold water takes place in the usual manner.

It is evident that a device of this kind can be employed whenever it is necessary and independently of any other source of heat than the burner itself and that it can be located at the mostconvenientpoint and without reference to a stove or range.

It will thus be seen that by extending the pipe D into the tank A in the manner described and by making a connection from the outlet-pipe G to the top of said tank and from the bottom of the latter to the laterally-extending heating-chamber E, I make provision for a positive upward circulation in the pipe G and a downward circulation in the tank, said downward circulation causing the water leaving the bottom of the tank to pass through the pipe F upward into the heating chamber E, the elfect of which is evident.

The advantages of such a structure are lnanifestfor instance, in warm weather-as it obviates the necessity of maintaining a fire in a stove or range for the purpose of obtaining hot water. As above referred to, however, the device can be used in connection with a stove or range without material change in structurefor instance, by employing the branch pipes J and K, leading to and from the range and communicating, respectively, with the pipes H and F. When thus communicating with the heating apparatus of the stove, the burner N may be used or dispensed with, as found desirable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a water-heater, a tank having inlet and outlet ports and an upright flue, a Waterholding heating-chamber of greater area than said flue situated below said tank and communicating with the upper end thereof by means of a pipe passing through said flue, the lower end of said tank communicating with said chamber, a burner situated below said heating-chamber, a hood surrounding said heating-chamberand having an open upper end forming a close joint from the bottom of the tank around said flue and a de pending flange extendingbetween the bottom of the tank and the top of the heating-chamber and provided with openings.
